✦ Synopsis

Annealing in air produces less photocurrent and a small IPC/IDC ratio compared t o those of unannealed CdS : Yb crystals. Annealing in sulfur makes the crystals very conducting without any increase due t o photoexcitation. Annealing in presence of Cd metal makes the photo-response quite fast. Results of photoconductivity excitation spectra are also presented and discussed.

## Abstract The effect of vacuum annealing on the properties of graphene is investigated by using Raman spectroscopy and electrical measurement. Heavy hole doping on graphene with concentration as high as 1.5 Γ— 10^13^ cm^βˆ’2^ is observed after vacuum annealing and exposed to an air ambient. This dop
